I can’t see where they would be so life threatening, they push the heim joints and they are or could be the weak link. Are the welds good? If not 1/4” steel that would be the only other problem. Basically the Chinese could make them identical to Calverts but pay the guy making them $2.50 to sell them that cheap and still make a tidy profit. The Chinese have good machinery they just don’t have to pay union wages
If the front mount, or the front heim breaks, and the front of the bar drops down, you have an incredibly dangerous scenario. Is that any more likely than a real caltrac setup? I don’t know.
